THREAD-CUTTING TEIVEELE FOR LOOMS.

Application filed October 8, 1925. Serial No. 61,194.

To all whom it may concern:

Be it known that I, JAMES A; SonnELLs, a' citizen of the United States,and a resident of Gainesville, county of Hall, State of Georgia. haveinvented an Improvement in Thread-Cutting Temples for Looms, ofwhich'the following description, in connec tion with the accon'ipanyingdrawing, is a specification, like characters on the drawing representinglike parts.

This invention relates to thread cutting temples for looms and theobject of the invention is to provide simple and eflicient means foreliminating the use of springs and for effecting the movement of theusual movable thread cutter member to open rearward projected positionby gravity.

The object and nature of the invention will be more fully understoodfrom the accompanying description and drawings and will be particularlypointed out in the claims.

The thread cutting temple is such a wellknown and familiar device inconnection with looms that it is unnecessary here to illustrate ordescribe with any degree of detail the construction and operation of anyparticular form thereof. For the purpose of disclosing a preferred formof the present invention, a well-known form of temple such as shown inthe patent to Draper and Stimpson, No. 585,465, granted June 29, 1897 isillustrated.

In the drawings:

Fig. 1 is a side elevation of a thread cutting temple with a preferredform of the present invention embodied therein;

Fig. 2 is a top plan view of the construction shown in Fig. 1.

Such a temple usually comprises the stand 1 by which the temple issecured to the loom, the shank 2 sliding'in the stand, and the head 3which forms the termination of the shank. This head is extendedlaterally to form the cap 4 and pod 5, between which the usual templeroll is mounted. The temple head is provided with a downwardlyprojecting heel 6 struck by the lay upon the beat-up in the usualmanner.

Such temples are commonly provided with thread cutting devices to cutthe ends of filling projecting from the selvage. In the drawings, a.right-handed temple is shown adapted to be used on the right-hand sideof the loom and provided with a thread cutsubstantial weight.

ting mechanism of the general type shown m'the Draper and Stunpsonpatent referred to. This mechanism comprises a movable cuttermembermounted to slide longitudinally and rock vertically in the temple head.

As illustrated, this member comprises a longitudinallyextending body 7terminating at the forward end in a depending heel 8 and atthe rear endin a pair of hook-shaped cut.-

ting blades 9 which straddle a fixed cutting blade 10 mounted at therear of the temple head. The movable cutter member is shown in itsrearward projected open position with the hooked bladest) elevated. Whenthe lay heats up and strikes the heel 8, this movable cutter member isrocked so as to swing the hooked blades 9 downwardly over any fillingendwhich may extend in front of the temple, and then the movable cuttermember is slid foravardly and such ends are thereupon severe I Thepresent invention relates to the means for effecting the movement of themovable thread cutter member to its open and rearward projectedposition. Heretofore it has been common to provide springs of variousconstructions for this purpose, and while such springs have been widelyand success fully used, they are, of course, subject to the objectionswhich are inherent in springs. They are subject to breakage. They notinfrequently wear into and cut away the studs on the movable cuttermember and temple head upon which they are mounted. They require careinthe manufacture.

In the'present invention, a weighted lever preferably in the form of abell crank is employed. This lever 11 is fulcrumed on a stud 12projecting laterally from the temple head. One arm 13 of this leverextends downwardly and is pivoted at its lower end upon a stud 14extending laterally from the heel 8. The other arm 15 extends forwardand is made of such a size as to constitute a This arm 15 preferablyextends substantially horizontally so that the full force of gravity onthis weight is exerted to rock the lever about its pivot.

. It will be seen that the arm 13 constituting a link between the studs12 and 14 controls the movement of the movable cutter member, which isotherwise guided in the temple head. It will also be seen that thepivotal connections between the lever and the stud,

12 and between the lever and the stud 14; enable smooth, extendedbearings to be provided which are little subject to wear.

The present construction may be readily embodied in existing templeswherein studs such as 12 and 1a are provided for the usual spring constaction, a lever simply being substituted for the spring and suitablemeans such as a nut 16 threaded on the stud 12 to hold the lever inplace.

The invention thus provides a construction which is durable, certain inits action, economical of construction and ittle subject to getting outof order.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is:

1. A thread cutting temple for looms having a movable cutter membermounted for vertically rocking and longitudinally sliding movement inthe temple,'and a lever fulcrumed on the temple, pivoted at one end tothe movable cutter member, weighted at the other end and acting to movethe movable cutter member to, and hold it yieldingly in, rearwardprojected open position.

2. A thread cutting temple for looms having it movable cutter membermounted for vertically rocking and longitudinally'sliding irovement inthe temple, and a bell crank lever tulcrumed on the temple with one armextending downwardly and pivoted at its lower end to the movable cuttermember and with the other arm ext-ending :torwardly and weighted, thesaid lever acting to move the movable cutter member to, and hold ityieldingly in, rearward projected open position.

3. A thread cutting temple for looms comprising a movable cutter memberhaving a depending heel and mounted for vertically rocking andlongitudinally sliding movement in the temple, a link connection betweenthe temple and said movable cutter member to control the movementthereof, and a weight movable with respect to the temple and actingnormally by gravity to move the movable cutter member to, and hold ityieldingly in, rearward projected open position.

In testimony whereof, I have signed my name to this specification.
